I was actively looking for something like this and had found this last week. Pine buds pro is another option that gives you quite a lot of control with access to the firmware. But I cant seem to get my hands on any of them. Either the custom duty doubles the price or it is too costly.

Nonetheless open-source ear buds is a big need for the engineering and hacker community.

Despite their recent massive flops in the AI department, in a way this makes me excited about Apple's prospects in this regard in the long term. These are bigger than AirPods, but they're not _that_ much bigger. Shave off the USB-C connector for wireless charging, swap the battery out to accommodate for the shape and you're already pretty close. Apple is really good at fitting things into the smallest form factor possible, and given they could offload all the compute to the iPhone which already comes with some pretty good chips, this could lead to some really exciting tech in the long run. They need to get their act together before that can happen though.

This is very cool project I need to say. I really like all the things that you build on top of that. I had no idea about the BMA550 accelerometer usage to detect speech and silences, it's very very cool.

Regarding the IMU, it mentioned the MM-FIT for workouts, but I checked the code and it's not used at all, no?

Good job, awesome product :-)

I'd love to buy this, but I can't afford 2500 euro for a personal fun project.

I have previously purchased and written[1] about the Tympan.org open source hardware hearing aid[2], but it's about $300 which I can reasonably purchase.

If this comes down in price, I'd love to build some neat things with this hardware.

This is pretty cool. Crazy price though (guess more of a devkit). Hopefully this will get adopted by others like Apple.
